SPECIFICATION forniing part of Letters Patent No. 424,155, dated March25, 1890.

Application filed April2'7, 1889. Serial No. 308,797. (No model.)

To all whom it may concern.-

Be it known that we, EDMUND WVILKOSHES- KY and LEE VAN ORTON, both ofButte City, in the county of Silver Bow and Territory of Montana, haveinvented a new and Improved Leaf-Turner, of which the folloing is aspecifi cation, reference being had to the annexed drawings, forming apart thereof, in which.

Figure 1 is a perspective view of our improved leaf-turner. a part ofthe leaf-turning mechanism. Fig. 3 is a front elevation of theescapement and leaf-carrying arms, showing the device in position toengage the first arm of the series. Fig. 4 shows the position of thedevice after the first arm has been carried over. Fig. 5 shows theposition of the parts when all of the arms have been carried over andthe carrier is in position to return them to the point of starting. Fig.6 is a transverse section taken on line at m in Fig. 3, looking in thedirection indicated by the arrow. Fig. 7 is a front elevation of aleaf-turner provided with mechanism for returning the arms, and Fig.8 isa'plan view of the same.

Similar letters of reference indicate corresponding parts in all theviews.

The object of our invention is to construct an instrument for turningthe leaves of books, music, and other papers for the use of pianists,organists, and for attachment to orchestral music-stands.

Our invention consists in a rack of any desired form supported by aframe, in the center of which is journaled a shaft, upon the upper endof which are loosely pivoted arms provided at their outer ends withclips for engaging the upper edges of the sheets, and in thecombination, with the said series of arms and shaft, of a carrierattached to the shaft and adapted to engage the several arms insuccession and carry them over, so as to turn the leaves as required.

The invention also consists in the combination, with the shaft, of apinion attached thereto and a rack and lever for turning the pinion, andthus, through the medium of the shaft, turning the sheets.

It also consists in the combination, with the rack, of an adjustableshelf for holding books and papers at diiferent heights.

Although our improved leaf-turner is de- Fig. 2 is a detail view ofsigned for use in connection with all kinds of printed matter, music,manuscripts, &c., we shall describe it as turning the leaves of music.

The rack A, which forms the support of our improved leaf-turner,consists of the frame a and the scroll-work panel I). In the center ofthe frame a, behind the scroll-work panel I), is journaled a shaft B,the upper end of which extends through abracket c and through the top ofthe frame a. Upon the upper portion of the shaft B, between the bracket0 and the upper part of the frame a, are placed arms (Z d (I d, whichare separated by washers e. The outer ends of the arms (Z d d (I carryspring-clips f, which are adapted to engage the edges of the leaves ofmusic.

To the shaft B, below the bracket 0, is secured a carrier C, which isformed of a section of a hollow cylinder arranged concentric withreference to the shaft B and attached to the shaft by an arm g and bossh. The edge "6 of the carrier G is provided with a finger j, which islocated a short distance from the upper edge of the carrier. Theopposite edge 7; is of sufficient width to engage the entire series ofarms (Z d (1 (Z in the manner presently to be described.

To the shaft B, near the lower end thereof and within the frame a, isattached a pinion l, between which and the said frame a is arranged aspiral spring m. In guides at, attached to the frame a, is placed a rack0, which is capable of engaging the pinion Z.

In the frame a is journaled a lever 19, which is formed of a rod benttwice at right angles or offset, the outer and lower arm being providedwith a handle q, the inner and upper arm being connected by a link 0'with one end of the rack o. The opposite end of the said rack isconnected with one end of the spring 3, the opposite end of which isconnected with the stud I, inserted in the lower part of the frame a.The lower end of the shaft B is provided with a handle a, by which itmay be drawn down or turned, as may be required.

To the frame a is fitted a movable shelf D, carrying at opposite endsspring-catches '0, which are adapted to engage rack-bars w on oppositeedges of the frame a and hold the shelf D at any desired height.

The music is placed upon the shelf D and its leaves are engaged by theclips f. The carrier 0 being in engagement with the arm (Z, the lever 19is tilted in the direction indicated by the arrow. This operation,through the engagement of the rack-bar 0 with the pinion Z, turns theshaft B and causes the carwith the arm d, the spring m of the shaft Bserving to push the shaft upward and bring the finger of the carrierinto engagement with the said arm. The second movement of the lever 19turns the second leaf of music, and so on. v I l I I WVhen it is desiredto return all of the leaves to the point of starting, the rack 0 isdrawn to the right by means of the handle g until the pinion Z is out ofengagement with the raclcbar 0 when the shaft B is turned, bringing theedge is of the carrier 0 against the arms (Z (Z (Z 0Z thus turning themall back to the point of starting. The shaft B is then turnedinto theposition it occupies afterturning a leaf. WVhen the handle a isreleased, the springs s m return the shaft B to its original positionand bring the carrier 0 again into engagement with the first arm cZ,when the operation'ju'st described may be repeated.

The adjustment of the shelf D up or down upon the rack A is for thepurpose of accommodating the leaf-turner to leaves and books ofdifferent sizes.

In the form shown in Figs. 7 and 8 an auxiliary shaft B is journaled inthe frame a, the said shaft being provided at its upper end with an armadapted to engage any or all of the arms cZ cZ, &e., and having at itslower end a. lever g, by which it may be turned. The said auxiliaryshaft B is furnished at or near its mid-length with a pinion Z ,which isengaged by a racko, arranged to move in the guide m. The rack 0 isconnected at one end with the retractile spring 8, and is provided atthe opposite end with a cam j, which is capable of engaging a pin rprojecting from the shaft B. The arm 70 is curved, as shown in Fig. 8,to enable it to engage the arms (Z (Z, &c., and carry them back to thepoint of starting.

The operation of this part of our device is as follows: After a leaf hasbeen turned, it it is desired to turn. it back, the lever q' is turned,thus bringing the arm is into engagement with the leaf-turning arm to beturned back. In its forward movement the cam 19,

carried by the rack 0, engages the pin 1', projecting from the shaft B,and pushes the said shaft B downward, so that the leaf-turning arm maypass the carrier 0. After turning the shaft B in the manner described itis returned to the position of starting by the retraetile spring .9.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. In a music-leaf turner, the combination,with the shaft B and the arms Z cl (1* (Z mounted loosely thereon, ofthe carrier 0, furnished with the finger j, andthe spring m, adapted tomove the shaft B longitudinally, substantially as specified, I I Y I 2.The combination of the shaft B, the arms (Z (Z (Z (Z mounted looselyupon the said shaft, the c'arrierO, adapted to engage the said arms, thespring m, the pinion Z, therack 0, and the lever 19, substantially asspecified.

3. The combination of the shaft- B, the arms (Z d (Z (Z mounted looselyon the said shaft, the carrier 0, adaptedto engage the said arms, thespring m, the pinion Z, therack o, the spring 8, and the lever p,substantially as specified.
